Good. If I download an app with the intent to pay a content creator who uses that app to post content, I don’t see why my choice of app store should have any bearing on how much of that money goes to the content creator, nor why the company who hosts that app on their store should get any income from said internal payments whatsoever.

Patreon (and everyone else) already pays Apple to simply host the app in their store. Apple is double-dipping by doing this and throwing an absolute fit comparable to that of a toddler who was just told “no”.
